Not only that it is painful, but it can also be very dangerous. There were some cases of testicle rupture from the low blow. This is a quite serious injury and it can make you sterile. In some martial arts such as Krav Maga, the low blows are something that is practiced in the trainings, so it is recommendable to avoid picking a fight with someone who practices this martial art if you want to avoid serious injuries.

The groin protector can help you withstand the direct hits to the groin without dropping into fetal positions. Yes, you will still feel the blow, but it will be much less painful.

Don’t fool yourself and think that you won’t need the groin protector if the low blows are not practiced in the martial art that you train. Accidents happen and you can be injured in the strangest ways.

No matter what martial art are you in, the groin protector is the most important piece of equipment you need. Even the girls can buy a female groin protector. Yes, it’s painful for them too.

The types of groin protectors

There are two types of protectors you can choose from. There are guards that you wear underneath the shorts instead of underwear. These are called compression shorts or jockstraps. And there are the protectors that you wear over the shorts.

The groin protectors that go over the shorts are mostly used for boxing. This is because the boxing utilizes only your hands for fighting and you don’t have to move your legs too much, so this type of protector is good enough to keep your family business safe.

The protectors that go underneath the shorts are much more versatile and much tighter. Because of this you can freely jump around or roll on the mat and the guard will stay in place.

Compression shorts vs jockstraps

There are two types of guards that you wear under the shorts. There are jockstraps and compression shorts. Jockstraps don’t feature the underwear and they only cover your groin so you can choose if you want to wear it over or under your underwear.

The compression shorts are basically underwear with a compartment in which you can put the guard. This is very convenient because you can easily put the guard when you need it and take it out when you don’t need it. However, the fit is not as good as it is with the jockstrap because you are not tying it up. But generally, this works for the most of the people and it is the easiest way of wearing the groin protector.

Everyone have their personal preferences when it comes to groin protectors and because of this the most of the manufacturers make both compression shorts and jockstrap versions of their protectors.

When to use a groin protector?

You only need to use the groin protector during a sparring and clinching. You can never predict if your sparring partner is going to hit you below belt and because of that, you need to be prepared.

If you know that you are going to have a sparring session in the class, bring your groin protector or even wear it to the training because that way you can’t forget to put it on.

Make sure that you have the groin protector in your bag always so that you are always prepared. Sparring against the people who can’t control their technique is the most dangerous for you. Because of their inability to control their technique, you can get hurt and injured and because of that, you need to be well protected.

If you train Brazilian Jiu-Jitsu it’s recommendable that you always have your groin guard on. This sport involves so much contact during the submissions and you need to protect your groin if you want to avoid pain and injury. It is also very nice to protect your partner from your junk on his face.

Consider these factors when buying the groin protector

Fit and comfort

The comfort of the groin protector is the most important factor you need to consider. The cheap protector, for example, will provide the proper protection but they are not comfortable enough and if your protector is uncomfortable, the chances are that you will not wear it.

This depends mostly on the design of the product. We all have different build and body type and the protector won’t fit the same for everyone. What guard will you choose depends on your personal preferences.

The easiest way to choose the most fitting groin protector is to read the reviews and user’s feedback and see what people dislike and like about the certain product.


The size that will fit you the best depends on the size of your waist. Each brand has the sizing directions to help you choose the proper size of the protector. Make sure that you don’t choose too big protector to avoid the cup movement while you practice.

Some of the protectors have cups that can fit everyone and you can adjust them by adjusting the straps. These usually don’t come with the straps and are made for wearing over the underwear.


Protection from impact is the groin protector’s job. It will do a great job if it’s made of hard material. The difference in the level of protection between different brands is not very big. Although the most of the companies will claim that their product offers the best protection, the broken groin protector is not yet seen.


This is the last factor to consider. You can always buy the groin protector in a local store for less than 20 bucks and it will protect you enough but it will not be very comfortable.

I would recommend that you choose a bit more expensive solution so you can get the proper protection and a perfect fit and comfort. This may seem like a bit too much money to spend, but you will buy the groin protector only once and then you will use it for years.

Of course, if you are on the budget, the cheap protector will do just fine if you don’t mind the moving in your pants and be uncomfortable. But if you are not on the budget, you should definitely buy one of the top brands.

Now that you know everything you need to know about the groin protectors, let’s go through some of the top products and see which the best groin protectors on the market are.
